The TC-ODD321 is a high-density digital output (DO) module designed for the Honeywell Experion PKS C200 platform. It provides 32 solid-state output points, organized as two isolated banks of 16 points, enabling efficient control of solenoid valves, indicators, interposing relays, and other discrete devices.
Built for industrial reliability, the module maintains high signal integrity under fluctuating thermal conditions. Its 16-point common architecture simplifies field wiring while ensuring electrical isolation between the two banks.

Discrete Control in High-Density Racks – Saves cabinet space while managing multiple devices.
Solenoid Valve Control – Efficient operation of hydraulic or pneumatic actuators.
Indicator and Relay Switching – Reliable signaling in control panels.
Industrial Automation – Process plants requiring high-point digital outputs with isolation.
Can the TC-ODD321 handle inductive loads without external protection?
While the module includes internal clamping and surge protection (1 A for 10 ms per point), it is recommended to use external flyback diodes or surge suppressors for highly inductive loads (e.g., large solenoids) to extend the module’s lifespan.
